HINGE.

Specification of Letters Patent.

Application filed July 22, 1909.

Patented May 24, 1910.

Serial No. 508,917.

To all whom it may concern:

Be it known that I, CHARLES GLovnR, citizen of the United States,residing at New Britain, county of Hartford, State of Connecticut, haveinvented certain new and useful Improvements in Hinges, of which thefollowing is a full, clear, and exact description.

My invention relates to improvements in hinges, the object being toprovide a hinge which shall be constructed of only two parts, the usualseparate pintle being dispensed with.

Figure 1 is a view of two companion hinge leaves separated, one of theknuckles being shown in section. Fig. 2 is an edge view of two blanksbefore the knuckles are rolled. Fig. 3 is a view of a completed hingeassembled, with parts of one lmuckle broken away. Fig. 4 is a relativelyenlarged plan View of a completed hinge. Fig. 5 is a horizontalsectional View of a hinge in process of construction, being partiallycompleted.

12 are companion hinge leaves. Leaf l is provided with knuckles, in thisinstance, three. These knuckles are indicated at 3 %5. The knuckles 3and 5 are arranged at the ends of the leaf 1 and have inwardlyprojecting conical extensions. The knuckle 4 is formed between theknuckles 3 and 5, and has two oppositely directed conical extensions.The leaf 2 is provided with two knuckles, 67 arranged to fit between andengage with the knuckles on the companion leaf. The knuckles 67 haveconically formed recesses in their ends, adapted to receive the conicalextensions on the companion knuckles. These conical projections andrecesses are formed in the following manner: Flat blanks of metal arefirst cut with tongue like extensions having beveled opposite edges soarranged that when these tongues are rolled up, the knuckles will beformed on the companion leaves provided with the aforesaid conicalprojections and conical recesses.

In Fig. 2 the tongues appropriate for forming the knuckles are indicatedrespectively by the reference numerals 3, 43, 5 6 7 To assemble thehinge the knuckles 8- l5 are first completely formed while the knuckles67 are partially formed, not being completely rolled up. When theseknuckles 67 are, say, half formed, they are passed through the space tothe rear of the conical extensions on the companion knuckles, so as toassume approximately the position indicated in Fig. 5, after which theknuckles 67 are completed, thus causing said knuckles to embrace andpermanently connect with the conical projections on the knuckles 345. Bythis simple means the necessity of a separate pintle is dispensed with.

What I claim is:

1. In a hinge composed of two parts or leaves of sheet metal, knucklesat the edge of one leaf, each knuckle having an integral end projectionforming a pintle, and knuckles on the companion leaf having end recessesarranged to receive and surround the pintle projections upon theadjacent companion knuckles, all of said knuckles being formed fromrolled up sheet metal.

2. In a hinge composed of two parts of sheet metal, forming leaves,integral interlocking knuckles arranged at the adjacent edges of saidleaves having cone-like extensions and depressions arranged to couplesaid leaves and to permit said leaves to turn relatively to each other,one of the knuckles on one leaf being arranged between two knuckles onthe adjacent leaf to prevent independent end play of said leaves, all ofsaid knuckles being formed of rolled up sheet metal.
